Literally googled “how to get along with your mother in law”

Just give me advice. I’m at my breaking point. It’s ruining my marriage. Making my pregnancy miserable and making me miserable. Doesn’t help that we all live together (they bought a house in the middle of our relationship) now we’re planning and saving to sell and buy just me and my husband but I don’t think I can hold on for two years. I’m going insane I’m thinking of where I can stay after I give birth cause I don’t want to be around her after. I’m just sick at this point just help me pleas! I started a journal to vent out my feelings but god knows I can take so much. He met me with me being independent, living on my own and I’m not trying to sound bitter but he’s such a mommy’s boy it’s sickening. He’s also Dominican so if you know anything you know the family is all stuck up eachotehrs asses. Not a bad thing but it comes to a point.
